SUMMARY OF EPOCH SOLUTIONS<br />

------------------------------------------------------------------------<br />

NUMBER OF EPOCH SOLUTIONS WITHOUT PROBLEMS: 2879<br />

NUMBER OF EPOCH SOLUTIONS WITH A BIG RMS: 0<br />

NUMBER OF EPOCH SOLUTIONS WITH TOO FEW OBS.: 0<br />

NUMBER OF EPOCH SOLUTIONS WITH "BAD" FLAG: 0<br />

TOTAL NUMBER OF EPOCH SOLUTIONS: 2879<br />

MEAN RMS OF THE EPOCH SOLUTIONS: 0.0084 M<br />

MAXIMUM RMS FOR AN EPOCH SOLUTION: 0.0273 M EPOCH: 1271<br />

MAX. CLOCK CORR. FOR AN EPOCH SOLUTION: 0.3300E+08 NS EPOCH: 18<br />

MIN. DEG OF FREEDOM FOR AN EPOCH SOLUTION: 4 EPOCH: 1738<br />

The clock jump detected in the baseline with the station Zimmerwald can of course again<br />

be seen as a clock event in the preprocessing of the zero-difference observation file. The<br />

magnitude of 33 ms corresponds exactly to the clock jump estimated in example 1:<br />

CYCLE SLIPS ACCEPTED IN THIS RUN<br />

NUMBER OF SLIPS IN L1: 27<br />

NUMBER OF SLIPS IN L2: 27<br />

2 JMP * 18 ALL 2 1 -40510800.000 (EQUIVALENT TO -33. MS)<br />

------------------------------------------------------------------------<br />

Because the correction of cycle slips is switched off when preprocessing zero-difference files<br />

this section should only contain JMP-entries (or nothing).<br />

The handling of detected clock events is reported in a part of the program output which<br />

appears only when preprocessing zero-difference files:<br />
